Product Name: Sprocket Turntable Model NO.: 300mm-1200mm Type: External Gear Rolling-Element Number: Single-Row Standard or Nonstandard: Standard Trademark: BEIGONG Transport Package: Tray Origin: Shanxi, China HS Code: 8708941000 Product Description Turntables are part for fitting onto trailers and agricultural vehichles to connect the A-frame to the trailer shassis so it can swivel. Their purpose is to transmit both the axial load, thrust and traction forces. None of their part is susceptible to wear. Each turnable consists of two steel ring designed for flange mounting. The raceways are machined so as to ensure that the load transmission is favorable directed between the antifriction bearing steel balls that are fitted. An initial filling of grease protects the raceway system.Technology and Specifications of Turntable:The turntable rings' rough are by casting, then we machine the rough rings, after that we do assembly and fill the balls, play grease, and then fit on the name plate and nipple, then do paint.Material of the rings: ductile cast iron(nodular cast iron), code QT500-7Hardness of ring:170-230HBSHeat treatment: Because ductile cast iron is with good wear-resisting property, so no need heat treatment.Tensile Strength: 500MPaMinimum Yield: More than 7%.Hardness of balls: 60-66 HRC, material is ball bearing steels SAE52100Machining Tolerances for diameter of outside ring: +/- 1.2mmTypePart No.ABCDCapacityWeightSection TypemmmmmmmmtonkgType UA1000-90UA1000100090846782UAType UB1200-90UB1200120890105912110UB1102-90UB1102111090945899UB1100-90UB11001108909591297UB1000-92UB10001010928591080UB1000-90UB10001008908591080UB1090-80UB10901105809726.585UB1000-80UB1000101580882680UB880-80UB88089580762570UB685-80UB68570080567350UBType Z1050-58Z105094558832560Z750-58Z75065658532447Z520-56Z52042656302330ZType U1200-94U1195120894107420118U
